ABSTRACT
This article reports the phenomenon of embryo rotation during its development inside the seed. This was first reported in the developing embryo of Polygala species. A survey of embryological literature in angiosperms shows that there are direct as well as indirect evidences for embryo rotations in many other taxa. Embryo rotation can also be caused by the rotation of the seed during its development as in some legumes. It is suggested that embryo rotation causes seedling handedness so commonly observed.
